I think whether or not it's clear that "her father" refers to Sofi's father would depend largely on the broader context of the paragraph. From this sample, it could go either way. I can certainly see where there would be a clarity issue and I also see that it could be taken properly. I think if you molded the prior and following sentence to add clarity, it could work just fine.

ETA: Sometimes when I run into sentences like these, I find a way to split it into two just to eliminate any possible confusion.

Thanks, guys. I like your suggestion @Wreybies. @SethLoki, yours works as well, but while I like that sentence the style would be out of place with the rest of the piece. @Spencer1990 I was considering splitting it into two, but I wanted to preserve the flow I had going if possible. I think Wrey's suggestion does that.
